To refresh your memory, the SLS AMG GT3 is the race-prepped version of AMG’s first bespoke supercar, and no, it’s still not exactly legal for use on the streets, but that’s not stopping AMG from building a small, specialized batch to celebrate its 45th year of existence. Only five examples – each identical in all but serial numbers – will be built.

So, what’s new this time around? The paint, for starters: dubbed magno graphite, it was only previously used on the 2013 SL65 AMG 45th Anniversary model. While it adorns virtually every body surface on the SLS AMG GT3, it’s also applied to the GT3’s wheels and roll cage structure. 45th Anniversary GT3s also receive big, boastful 45th anniversary graphics on the doors. In an interesting twist, the “45” numbers aren’t painted; instead, they expose the woven pattern of the carbon fiber used in each door.

The interior remains a gutted, business-oriented affair, though GT3 45th Anniversary models do receive one convenience-oriented feature: a second carbon fiber-shelled seat, allowing a passenger to ride shotgun during hot laps. Six-point harnesses are trimmed in silver, as is the steering wheel. Special badges applied to the seatbacks and center console bear the car’s sequence number.Mechanically, the SLS AMG GT3 45th Anniversary Edition is no different than any other SLS AMG GT3. A big, brutal 6.2-liter V-8 cranks out over 600 hp, and drives the rear axle by way of a six-speed sequential manual transmission. On the plus side, AMG says the engine’s assembly and installation will be managed to by none other than Bernd Schneider, five-time DTM champion and AMG brand ambassador. Buyers will receive a certificate of authenticity signed by Schneider, and if so desired, additional driver training at the AMG Driving Academy.

Want one? Prepare to pony up a princely sum. At roughly $515,000 SLS AMG GT3s aren’t cheap in the first place, but the 45th Anniversary models should fetch at least $579,000 in Germany, including VAT.Source: Mercedes-Benz
